Abstract
Recent improvements in ultrasonography have made it possible to gain much more information by allowing the visualization of tissue construction, organ movement, and fine blood flow in the oral and pharyngeal area. These improvements enable observation of the three-dimensional structure and movement of the oral cavity and pharynx, and could contribute to rapid advances in oral and pharyngeal ultrasonography.
We focused on the usefulness of ultrasonography in the screening and primary care of malignancy in the oral cavity and pharynx.
